Perhaps Close, and her father, were with a part of MRA that practiced them in the extreme. Or perhaps her father was a domineering, patriarchal type, and MRA provided a rationale and framework for him to justify personal authoritarianism.
Moral Rearmament came out in the interwar period, and was based on the belief that radical Christian living could transform individuals into more loving people, and if this spread, could lead to world peace. They deliberately targeted leaders in business, academia, and government. For a while they were active in (early) Nazi Germany, but were eventually closed down. Because of their outreach to leaders, they were regarded by many as spiritual elitists. Known first as "the Oxford Groups," it was considered a spiritual movement, and not a religion, and its "Six Steps" were the foundation for AA's Twelve.
Close noted, in the brief article, that she called her father, "brilliant, brilliant..." and MRA as "cult-like religious group," -- not quite a cult. My guess is the issue is the father-daughter relationship, not the spiritual one.
